How can I effectively perform seated chair push ups to strengthen my upper body muscles?

To effectively perform seated chair push ups to strengthen your upper body muscles, start by sitting on the edge of a sturdy chair with your hands placed shoulder-width apart on the seat. Keep your feet flat on the floor and slowly lower your body towards the floor by bending your elbows. Push yourself back up to the starting position by straightening your arms. Repeat this movement for a set number of repetitions to target and strengthen your chest, shoulders, and triceps.
